If you're watching your calories but still wanting to enjoy the festive day, you might think it's proper for you to avoid the famed Irish Guinness, but we're here to share some good news: You're wrong!

Guinness, in fact, is just the brew your St. Patrick's Day celebration needs. And it's way better than that funky dyed green stuff. Here, 3 reasons Guinness Stout should be your go-to St. Patty's day beer.

1. It's deceptively rich.

It may drink like a meal, but Guinness has only 15 more calories than Bud Light, and just 10 grams of carbs.

The nitrogen adds major creaminess. That velvety mouthfeel and pillowy foam head come from nitrogen rather than CO2, giving it uniquely smooth effervescence.

2. Perfect pours take patience.

Savvy barkeeps know to pour Guinness in two "shifts," so the foam can settle. The ideal pour is said to take 119.5 seconds.

3. It has a low ABV.

Guinness is only 4.2% alcohol by volume, which helps with decision-making on Shamrock Day—like, is it time for another round?
